Abstract

A vehicle seat is obtained capable of suppressing the occurrence of wrinkles in natural leather employed in a cover while suppressing a reduction in seating comfort of the seat. A non-woven fabric is disposed between a foam member and a foam member, so as to cover a portion of contact with the buttocks of a seated occupant, as viewed from above. The non-woven fabric suppresses extension and contraction of natural leather at the pressed portion, thereby suppressing the occurrence of wrinkles in the natural leather at the pressed portion. By only suppressing the extension-contraction amount of the natural leather at the portion where wrinkles are liable to occur, the occurrence of wrinkles in the natural leather can be suppressed while suppressing a reduction in the seating comfort of the seat.

Claims

What is claimed is: 
     
       1. A vehicle seat comprising:
 a seat cushion that supports the buttocks of a seated occupant;

 a multi-layer cover member that configures a portion of a cover covering the seat cushion or the seatback, and comprises natural leather disposed at an outer surface of the multi-layer cover member, a plate shaped first foam body adhered to the inside of the natural leather, a plate shaped second foam body adhered to the inside of the first foam body, an inside non-woven fabric adhered to the inside of the second foam body, and an intermediate non-woven fabric adhered between the first foam body and the second foam body at a location of contact of the natural leather with the body of the seated occupant. 
 
     
     
       2. The vehicle seat of  claim 1 , wherein the intermediate non-woven fabric is provided at a location of contact between the buttocks of the occupant and the multi-layer cover member. 
     
     
       3. The vehicle seat of  claim 2 , wherein:
 the seat cushion comprises side support portions that protrude out further than other locations and suppress the seated occupant from sliding in the seat width direction, a main portion that is disposed between the side support portions and supports the buttocks of the seated occupant, and a main front portion that is disposed in front of the main portion and supports the thighs of the occupant; and 
 the multi-layer cover member covers the main portion.
